' Florida corporation of A y y Application October 16, 1950,` Serial No. 190,324 I (ciao-6s) f 3 Claims.

This invention relates to an all-weather doorsill seal.

An object of the invention is the construction of an efficient device which will cause a seal on the floor or a seal against a door-sill, for the purpose of keeping out driving rains. snows, and cold air.

Another object of the invention is the construction of an' eiiicient device that can be positioned in diiferent places, such as on a door that opens from the left, or on doors opening outwardly.

A still further object of the invention is to produce an eflicient device that will t tightly the door and jamb, as well as sealing the door against drafts and other disagreeable conditions. Further, this device will function with or without a door-sill.

Also the device will help to eliminate outside noises.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in front elevation of a device constructed in accordance with the present invention.

Figure 2 is an enlarged fragmentary longitudinal sectional view of the device.

Figure 3 is a transverse sectional view taken on line 3-3, Fig. 2, and looking in the direction of the arrows.

Figure 4 is a fragmentary, longitudinal, section view of the device, vshowing the same in an open position.

Figure 5 is a transverse, sectional view. taken on line 5 5, Fig. 4, and looking in the direction of the arrows.

Referring to the drawings, in which the preferred embodiment of this invention is illustrated, I designates the sill, 2 is the door, and 3 is the door frame.

Fixedly secured to the door 2, near the bottom thereof, is a housing 4. The housing 4 is provided with an apron 5. Extending from the inner face of the housing 4, and projecting horizontally therefrom is a cam pin 6. l

A hollow cylinder 1 is in the housing 4. Thi cylinder 1 has a slot B extending its full length. In this slot 8 is clamped and held in an operating position a weather-strip 9. This weather-strip 9 is formed of any suitable material, such as rubber.

The metal cylinder 1 is formed of suitable material Y to permit a slight expansion while the weatherstrip 9 is being inserted in the slot 8 and upon releasing the cylinder after the weather-strip has been inserted, the cylinders slot-edges will clamp directly upon the weather-strip, securely fastening said weather-strip upon the cylinders. The cylinder 1 is also provided with an inclined cam slot Ill, into which'extends the cam pin 6.

The hollow cylinder 1 isprovided at each end with a socketed plug II. This plug II has an annular groove I2, into which is snapped the inwardly extending tits I3, formed on the cylinder 1. The resiliency of the cylinder 1 permits this action of placing the tits I3 in the annular groove I2. A cup-shaped spring holder I4 is loosely mounted in the cylinder 1. This spring holder always bears at its outer closed end against the cam pin 6. Extending at one end into the cup-shaped spring holder I4 is a coil springy I5, and the opposite end of said spring extends into the socket IIa of plug II, as clearly shown in Figures 2 and 4.

A metal abutment I6 is placed on the door frame 3 in a registering position with the plug I I. Therefore, when the door is closed, as shown in Figure 2, the abutment I6 will be pressing against the plug II. The weather-strip 9 will be engaging the sill I (Fig. 3). When the door is opened, the spring I5 will force the cylinder to slide outwardly, resulting in cam pin 6 being placed near the top of cam slot II), whereupon the weather-strip will be held raised, as shown in Fig. 5. Therefore, it will be understood that the cylinder 1 has both a sliding and a rotary movement within the housing 4.

The inclined cam slot I0 and the cam pin 6 constitute cam means for assisting in turning the weather-strip 9 to a closed or open position.

The operation is as follows: When the door is moved kfrom its open position (Fig. 4) to its closed position (Fig. 2), the plug II will have engaged the abutment I6, causing the cylinder to slide inwardly, and by reason of the cam pin 6 being in the inclined slot I0, the cylinder 1 will also rotate, placing the weather-strip 9 against the sill or iloor.

' 3 What we claim is:

1. In a device of the class described, the combination of a housing provided with a cam pin, a rotatable and slidable hollow cylinder in said housing, said cylinder provided with a cam slot, said cam pin in said slot and extending into said cylinder, closure means on one end of said cylinder, a cup-like spring holder loosely mounted in said cylinder and bearing at its closed end against said extended cam pin, a cushioning member extending at one end into said cup-like spring holder and bearing: at one end against said closure means. and a Weather-strip mounted only on its inner face, a rotatable and slidable,

hollow cylinder in said housing, said cylinder provided with a cam slot, said cam pin in said cam slot and extending into said cylinder, a plug provided withan annular slot. mounted in one end of' said cylinder, saidV cylinder provided with inwardly extending tits in said annular slot, a cup-like spring holder in. said cylinder and bearing at its closed' end againstv said extended cam pin, said plug provided withv a socket, a coil spring having one end -in said socket and its other end in said cup-like .spring holder,- and'A a. weatherstrip extending intosaid hollow cylinder, substantially as shown and described;

3. In a device of the class described. the combination of a housing provided with an inwardly extending cam pin, a rotatable and slidable hollow cylinder in said housing, said cylinder provided with a cam slot, said cam pin extending through said'cam slot, and projecting into said cylinder beyond its inner wall, a plug provided with a socket in its inner face and closing the end of said cylinder nearest to said cam pin, a spring holder provided with a closed end against the extended inner end of said cam pin and with an open end registering with the socket in said plug, a coil spring only between said spring holder and plug and said coll having one end in the socket ofLsaid plug and also having one end extending intollsaid spring holder through its open end.
